|Mary Jo Duffy|
February 9, 1954|
New York City, United States
A native of the New York City area, Duffy attended Wellesley College. As a young woman, she had letters published in Marvel Comics letter columns in the mid-1970s. She made an in-comic appearance as an autograph seeker in Iron Man #103 (Oct. 1977). Her first credit as editor appeared in The Defenders #61 cover dated July 1978.
Her writing work for Marvel included Conan the Barbarian, Fallen Angels, Power Man and Iron Fist, Star Wars, Wolverine, and a St. Francis of Assisi biography Francis, Brother of the Universe. Her run on Power Man and Iron Fist was the longest and most successful of the series, and was noted for using a lighthearted, tongue-in-cheek approach at a time when Marvel was pushing darker and more serious stories.
In the 1990s, she worked for other publishers, including DC Comics, where she wrote the first 14 issues of Catwoman. For Rob Liefeld's Extreme Studios imprint of Image Comics, she wrote every issue of the first Glory series, between March 1995 and April 1997, the last six of which were released by Liefeld's Maximum Press after his departure from Image.
In the early 2000s, she wrote issues of Marvel's Defenders, while working at a financial services company in Lower Manhattan. Her work at that company included meeting planning, editing, proofreading, and packaging for a comic book published by the company. She now works as a receptionist at the U.S. Immigration Office in New York and has been largely absent from the publishing scene. She made multiple announcements on her Facebook page that she created a new company to self-publish her work and incorporated Armin Armadillo Publishers in 2008. As of 2013, the company is listed as inactive.

My name started appearing on comics on a series of gushy but extremely sincere fan letters around '72 or '73.…That was before e-mail so if you got a letter printed you were like 'Oh cool!' and you'd exponentially send many more letters.
